Construct an ndarray that allows field access using attributes. Arrays may have a data-types containing fields, analogous to columns in a spr

An array class with possibly masked values. Masked values of True exclude the corresponding element from any computation. Construct

Dummy object that just exists to hang __array_interface__ dictionaries and possibly keep alive a reference to a base array.

Formatter for subtypes of np.floating

Exception thrown when there is a problem parsing a configuration file.

Class for masked array related errors.

An object that not only contains a reference cycle, but creates new cycles whenever it's garbage-collected and its __del__ ru

Type signature for a ufunc. Attributes ---------- type : str Character representing the nominal type. func_data : str or None

Wrapper for a Fortran routine for which the corresponding file is not known.

Container object for the variables defined in a config file. `VariableSet` can be used as a plain dictionary, with the variable names as

Wrapping a MaskedArray rather than subclassing to test that ufunc deferrals are commutative. See: https://github.com/numpy/numpy/issues/1
